Title: Visually symmetric removable low protrusion tensioned sign display system
Inventor: WITTENBERG RON LEO
IPC: G09F15/00
Filed: 1998-06-01
Granted: 2004-08-24
Abstract: A specially engineered, low protrusion, visually symmetric small footprint system of mounting advertising displays to vehicles, such as trucks, tractor trailers, and vans, providing upward/downward adjustability, ease of frame removal and remounting, and over-center tensioning by means of specially designed rails which are attached to the surface of the vehicle. The rails are reversibly fastened to the surface of the vehicle, and can be easily and repeatedly removed and refastened in a short time. This is effected by sinking threaded screw seats into the wall on which the sign frame is mounted, providing permanent holes into which can be repeatedly screwed into and unscrewed from, the low protrusion screws which hold the sign frame to the wall. The hardware residue, after removal of the frame, is barely visible, with a very small footprint, being simply the protruding rims of the threade d screw seats. The entire system, when loaded with signage, and tensioned, protrudes very slightly from the surface of the vehicle, capitalizing on the total width tolerances to within which large trucks and tractor trailers are constructed, and designed not to increase such width beyond applicable regulatory maxima when fully operational. The system is designed to facilitate the mounting of state of the art flexible advertising or publicity media at tensions which practically maintain the signage in a virtual plane, thus enhancing readability and reducing imag e distortion to the viewer yet do not put such strength demands on the mounting system such as to require a large footprint or permanent complex hardware appendage to the vehicle. Additionally, the parts comprising the anchoring and tensioning rails are only two in number, thus allowing for ease and economy of manufacture, as well as simplifying the inventory and installation processes. Due to the symmetric a nd streamlined mounting aspects of this system, it also lends itself well to bringing visually sleek and symmetric, removable tensioned small footprint signage to the fixed billboard market.

Abstract: In a method for casting prefabricated products in a continuous casting device, having a casting mold and a strand guide downstream of the casting mold, wherein the strand guide has rolls positioned opposite one another in pairs for supporting and guiding the solidifying cast strand, wherein some rolls are drive rolls and others are idle rolls, wherein drives are provided for the drive rolls, and wherein the drive rolls are adjustable against the cast strand in order to transmit guiding forces and strand conveying forces onto the cast strand in interaction with the idle rolls, the drive rolls and the drives are controlled to a preset rotational speed such that the drive rolls have circumferential speeds identical to one another within the limits of a preset casting speed. The motor torques of the drives are maintained at a level as equal as possible below a permissible torque limit value relative to a loadability of the strand shell. For a single drive and corresponding drive roll the permissible torque limit value is measured by continuously increasing the drive torque starting at zero and monitoring the rotational speed of the drive roll, while the remaining drive rolls are controlled to a preset nominal casting speed. For a superproportional increase of the rotational speed, the torque limit value is determined and the process is stopped.
